Liquid-fuel burner



HENRY J. OF

SAUKVLLE,

LIQUXDFUEL BURNER.

Application led April 30, 1918, Serial No, 231,582.

lle it lin-own that l, Hanni J. {li-ini'. a `citizen of the United States, and resident of tauxrille, in the county of @zaulree and State of ldfisconsin, have invented new and useful improvements in Liquid-Fuel Bur ners9 of which the following is a description, reference being` had to the accompanyingl dra-wings, which are a part of this specification.

My invention relates to liquid fuel burners and more particularly to a burner using` kerosene as fuel.

lu kerosene burners it necessary to pro ride a .means for raporizing the fuel pre vious to its ignition in tie burner. l am aware that it has been proposed to place the vaporizer directly above the burner or to provide an annular vaporizing conduit sur.- rounding` the burner head, but in these constructions the vaporizer is heated to such a high temperature as to crack the constituents of the fuel and produce an inei'iicient mixture. To obviate this diiiiculty l have provided a new arrangement and novel combination of parts whereby the vaporizer is only subject to a portion of the heat generated by the burners so that just enough heat is imparted to the fuel to cause etlicientvaporization.

The invention further consists in the novel parts and combinations of parts hereinafter described.

In the drawings:

Fig. 1 is a. plan view of the burner embodying the invention, parts being broken awayv and parts being; shown in section;

Fig'. 2 isJ a section taken on the line 2 2 of Fig. 1;

Fig. 8 is a section taken on the line 3-3 of Fig. 2;

Fig. l is a detail section taken on the line 4 4 of Fig. 2.

ln the drawings numeral 5 designates the circular burner body having a mixing` or expansion chamber 6 therein, and provided with a burner head in communication with said chamber.

The mixing chamber 6 is formed by the circular wall 7 of body 5, a channel 8 extending from one side of the body to and lbeyond the center of the chamber, said channel being' formed by partitions 9 extending inwardly from the wall 7, a deilector 10 disposed adjacent the outlet 1l of the channel B to divide the mixture passing through the Renewed .November 2'?, 12122.

`channel 8 into two streams withii the mixing chamber auf" thus provide for or-oper univ 1 +1 D fm? l n *l 5 7 fn no. oi no mixture. ine i, iannei is oper. at ilet end 1:2 to admit air and the vapori ed fuel The top irl of the mixing; chamber is prorided with plurality of ra.-

dially disposed openings llland other open l5 adjacent the channel 8 to conduct ie mixture from said chamber to the burner head.

rlhe burner head is formed by the top of he body 5 and a removable plate or can lli'.

t formed by an upwardly and outwardly n tl ...i rss inclined flange 17 on the body having; ra dially disposed. iurmrdly extending i uardly inclined projections 18 and the caJ 6 being` spaced from the top 13- by short ugs 18a to forni a passageway 191 and han ing; radially disposed outwardly extendino` upwardly inclined projections 2O which disposed in the recesses 21 formed by the projections 18 but which are spaced from said projections to form a circular corrugated passage or series of passages between the flange 17 and cap 16 through which the fuel passes from the passageway 19 The burner may be supported in. any suitable manner as by an upright 253 secured to a. centrally disposed lug 2e on the body rllhe vaporized fuel is introduced into the mixing channel 8 by means of a spray nozzle 25, the passage of fuel therethrough beine' controlled by a needle valve 9,6 adjustablr mounted in a threaded plug 27 secured adjacent the nozzle.

lnthe construction thus far described th j fuel from the nozzle 25 and the air enter the channel 8 and are partially mixed and then pass into the divided mixing chamber 6 from whence the mixture passes through the openings 14 and 15 into the passageway 19 and thence through the passage and is then ignited and burns above the burner head.

l do not claim that the construction above described is original with me7 but l illustrate it and describe it for the purpose of showing a construction which is capable of use in combination with the new and novel parts now to be described which parts it will be understood may be used in combination with any suitable form of mixing chamber and burner head.

lily invention. resides in the aid vapori iol izing means and their combination with the burner.

The vaporizing means consists of' a vaporizing tube 28 disposed at one side of the body 5 and secured thereto by a clip 29 and screws 30, said tube being connected at its lower end 3`l-to a fuel supply pipe 32. rIhis tube 28 extends upwardly along side the burner head and thence downwardly, the spraying nozzle and needle valve previously describedl being located adjacent the end 83 of said tube.

Clip 29 has one end projected beyond the body 5, as shown clearly in Figure 3 of the drawing, and thereby provides a free end forming a spring clamping means which can be adjusted to the vaporizing pipe, either tight or loose as desired, by lmanipulating the single screw 30 which engages said free end.

The means for heating the vaporizing means consists of a portion of the heat from the burner which is diverted from the burner head against the tube by means of a deflector. This deflector consists of a hood formed over a portion 34 of the burner head and having a side opening 35 adjacent the tube 28 formed with a vertical straight portion having integral thickened walls for a portion of its length and so that the burning` fuel of this segregated portion of the burner furnishes sufficient heat to the tube 28 to cause efficient vaporization of the fuel passing therethrough. rIhe hood is formed by a. top plate 3G, an inner side wall 37, an end wall 38 and an end wall 39. The top plate 36 extends inwardly over the portion 34 of the burner passage 22 and the side wall 37 is formed by a flange depending :from this top plate and disposed adjacent the inner side of the burner passage 22. The end wall 38 is formed by a flange depending from the end of the plate 36 and has an outwardly extending curved portion 4l() disposed adjacent the tube. 28. The end wall 39 is one end of a partial ring section l1 which is secured to the end portions of the top plate 36. The ends of the wall 37 are spaced from theinner ends of the walls 38 and 39 to form channels 42 to allow air topass insidel the hood adjacent the flange 37. The ring section 4l has an upwardly and inwardly inclined wall lf3 disposed adjacent the burner passage 22 and a continuous. groove 44.- seated on the upper outer edge of the body 5.

1With this construction the burning fuel of that portion of the burner head which is covered by the hood has its heat deflected outwardly against the tube 28 which is heated sufficiently to produce a more efficient vaporization of the fuel as it passes to the spray nozzle. 25 than would be the case were the tube 28 subjected to the whole or a greater portion of the heat from the b-urner.

I am aware. that the details of construction herein shown and described are subject to modification and change, but such changes as come within the scope of the appended claims I deem to be withinthe spirit of my invention.

TWhat I claim as my invention is:

In a device of the class described, a burner-head, a vaporizing-pipe, and a. heat deflecting means mounted on the burnerhead to deflect a portion of the heat from the burner to the vaporizing-pipe, said vaporizing-pipe being formedl with aI vertical straight portion having integral thickened walls for a portion of its length to provide bosses adapted to be positioned below the plane of the body-portion of the burner, one of said bosses having formed therein a spraynozzle and the other a threaded opening to receive a packing-plug, and a bowed holding-clip partially surrounding the vertical straight portion of the vaporizing-pipe and secured on opposite sides thereof to the bodyportion of the burner by screws, whereby the vaporizing-pipe can be bodily adjusted vertically with respect to the burner and its heat deflector by loosening the screws of' the holding clip.

In testimony whereof, I afiX my signature.
